# WHATPORT(8010)

## NAME

port 8010 — Buildbot web UI (IANA: Reserved) — Reserved at IANA; in practice the Buildbot master's web interface.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA marks 8010 Reserved rather than assigning it, which leaves the number to convention. Buildbot's own tutorial has you open `http://localhost:8010/` after starting a master, so a CI host with 8010 open is very often a Buildbot. Nmap's database labels it `xmpp` for XMPP file transfer, another historical use. Both are guesses until you read the response.

## EXPOSURE

**Expose with care.** A Buildbot web UI shows build logs, worker names and configuration to anonymous visitors unless authentication is configured, and build output routinely contains internal hostnames and secrets.

## CHECK

```sh
curl -sI http://TARGET:8010/
```
